Tran-REPAIR TOOL.

.Application filed July 2,

To (ZZZ-whom wit may concern."

Be it known that I, HARRY R. Hmsr, a citizen of the United States,residin at Trenton, in the county of Mercer and tate of New Jersey, haveinvented certain new and useful Improvements in a Tire-Repair Tool, ofwhich the following is a specification.

J. y invention relates to a tire repair tool, ada ted for inserting aplug in a tire, particu arly the outer shoe or casing of an auto- When atire has received a puncture, the life of the'tire will be prolonged ifthe tire is repaired by plugging the hole to exclude sand and water, andthe object of my invention is to provide a tool for inserting a rubberplug in the tire after it has received a puncture; a further object ofmy invention is to rovide a tool with which a plug, having a cadthereon, may be inserted in a tire, in either direction, so that thehead of. the plug will be ositioned u on either the inner surface or t eouter sur ace of the tire, according to the size of the puncture in thetire.

Referring to the accompanying drawing; Fig, 1, is a view in elevation,partly in section, of the tool and showing a tire in dot and dash lines;Fig. 2, is a view in elevation showing the parts of the tool detached;

Fig. 3, 1s a sectional view of the sleeve member of the tool showing howa plug is inserted with the head on the outside of the tire; Fig. 4, isa transverse sectional view of a portion of a tire showing the plug asillustrated in Fig. 3, after the tool has been removed; Fig. 5, is aview similar to Fig. 3, showing how a lug is inserted with the head onthe inside of the tire, and Fig. 6, is a view similar to Fig. 4:,showing the plug, as illustrated in Fig. 1-, after the tool has beenremoved.

In the accompanying drawings, in which like reference characters referto like parts 1 illustrates a rod having a head 2, formed upon one endthereof. The head is tapered and provided with a screw-thread, such asformed upon large wood screws. A shoul- 1924. Serial No. 723,624.

adapted to be loosely mounted upon the rod 1, Said sleeve is providedwith transverse holes 9 and 10 located at either end thereof. One ofsaid holes 9 or 10 will align with the hole 5 in the rod 1 when thesleeve 8 IlSTJPOIl the rod with the end of the sleeve abutting againsttheshoulder 3 of the rod, thus permitting the handle 6 to be readilyinserted through both the rod and the sleeve, as I shown in Fig. 1.

The tool is inserted into a puncture in the tire 12 by turning the toolso that the threaded head will force its way throu h the tire, thepuncture in the tire may he thus enlarged so that the sleeve 8 willenter the tire, as shown in Fig. 1. The threaded head stretches thematerial of the tire and increases the size of the puncture, but doesnot cut away, or roam, the material of the tire.

. The handle 6 is withdrawn, which pen mits the rod 1 to be withdrawn,thus leaving the sleeve 8 remaining in the tire, as shown in Fig. 3. Arubber repair plug 14 is inserted into the tubular recess formed ateither end of the sleeve 8 and the handle 6 is inserted in the sleeve 8.As the sleeve 8 is provided with holes 9 and 10 located at opposite endsthereof, the handle may be inserted in the hole at the opposite] end ofthe sleeve from the end containing the plu 14. 1

I it, is desired to insert a plug with a head on the outer surface ofthe tire, the handle 6 may be attached to the sleeve 8, as shown in Fig.3, so that the sleeve may be dpulled towards the inside of the tire l2'plug can be inserted at the inner end of the sleeve 8, as shown in Fig.5,and the handle 6 inserted through the hole at the opposite end of thesleeye. The handle can thus be pulled to withdraw the sleeve and allowthe head to remain on the inside of v the tire, as shown in Fig. 6.

Cement may be placed around the head of the plu before it is drawntightly into the tire an the protruding shank, or small end of the'plug,may be engaged with a pair of pinchers and pulled to stretch the shankso that cement can be placed around the shank and when released theshank will draw the cement into the tire. Theprotruding portions of thehead or shank of the plug may be readily trimmed off, as shown in Figs.

4 and 6.

I claim 1. A tire repair tool comprising a cylindrical member adapted tobe insertedinto an aperture in a tire said member adapted to receive arepair plug which is to be inserted in the aperture in the tire, saidmem her having transverse holes formed through i the same locatedadjacent to eitheren'd thereof, and a bar adapted to be inserted intoeither of said transverse holes in said member adapted to form adetachable handle for either pushing'or' pulling said member through thetire.
